Sixty-nine percent of local authorities in England have reduced funding for stop-smoking services due to budget cuts. These services are crucial for smokers' successful cessation, with specialists three times more likely to help them quit.
A new study finds that quitlines are reaching more smokers from diverse racial groups. Quitline users represent only a small percentage of tobacco users in each group, but the service can help reach underserved populations.
A study identifies telltale genetic fingerprints associated with smoking tobacco, demonstrating that smoking increases cancer risk by causing somatic mutations. The research found over 20 mutational signatures linked to tobacco smoking, with some signatures elevated in cancers from smokers.
Researchers identified distinct mutational signatures associated with tobacco smoke, including Signature 4 and Signature 5. These signatures are linked to specific types of cancer, such as lung and larynx cancers, and may be driven by a cytidine deaminase enzyme or other unknown mechanisms.

The development of global standards for vaping products is essential to promote innovation and protect consumers. Different regulatory approaches in the EU and US can hinder growth and stifle innovation, as noted by British American Tobacco's Head of R&D, Marina Trani.
People who have recently attempted to quit smoking are more likely to try to drink less alcohol. They report lower levels of alcohol consumption and are less likely to binge drink compared to other smokers. This finding goes against the common assumption that quitters tend to increase their drinking.
Researchers found that despite a ban on menthol cigarettes, similar products with green coloring and 'smooth taste redesigned without menthol' are being marketed to undermine the effectiveness of the ban. The study suggests that these tactics could have an adverse impact on public health.
A modeling study suggests that e-cigarettes are likely to provide public health benefits for adults, particularly adolescents and young adults, who use them instead of smoking. The study found a 21% reduction in smoking-attributable deaths and 20% decrease in life years lost due to e-cigarette use.

Leading tobacco researchers call for UK government to stop subsidizing films with smoking imagery and increase funding for anti-smoking media campaigns. The current system has led to a significant drop in spending on such campaigns, while providing £473 million in tax breaks to top-grossing films featuring tobacco imagery.
Genetically modified tobacco plants lacking jasmonates are more susceptible to insect and vertebrate attacks, with a significant impact on reproductive ability. Rabbits prefer to feed on these plants, peeling the stems and reducing flower production, highlighting the importance of nicotine in plant defense.
A new study finds that e-cigarette manufacturers make numerous unproven health claims, which may have a lasting impact on consumers. The FDA regulation aims to prevent such misinformation and ensure accurate information about e-cigarette use.
A study published in BMC Public Health found that nearly a quarter of US adults reported looking for information on tobacco constituents, with young adults and smokers more likely to do so. The research suggests that making this information available could improve public health and reduce tobacco use.
